Answer:

70.4metres

Step-by-step explanation:

Wheel Diameter = 0.7m

Wheel Radius; 0.7m / 2 = 0.35m

For one rotation of the wheel, the distance travelled = circumference of the wheel.

Circumference = 2 x pi x radius

= 2 × π × r

= 2 × π × 0.35

= 2.1991148575 m

Elaine tries to ride the unicycle and manages to go in a straight line for 32 full revolutions

Distance travelled with 32 full revolutions of the wheel = 32 x 2.1991148575 m =

Distance in meters = 70.37167544m

Approximately = 70.4m

Therefore, Elaine managed to cycle 70.4metres

Answer:

a+c=27

195a+320c=6515

Step-by-step explanation:

adult (a): 195

children (c): 320

total $: $6515

child $: 27

a+c=27 --> c=-a+27

195a+320c=6515

sub the first equation into the 2nd equation to get a=17

sub a=17 into c=-a+27 to get c=10

so, an adult ticket is $17 and a child ticket is $10.

Answer:Time = 1/9 Hours  0r  0.11111 hours

Step-by-step explanation:

We Know that Speed = Distance / Tim\e

Using the constant rate of the speed given as 27 miles per hour at

Distance = 3miles

Time = Distance  / Speed

Time = 3 miles / 27miles per hour = 1/9 hours

Answer:

Step-by-step explanation:

AB // DC

∠B + ∠C = 2x + 15 + x = 180

3x = 165

x = 55

Answer: B. 55

Step-by-step explanation:

You need to know that within one parallelogram, the same-side interior angles are supplementary angles, meaning that they add up to 180°.

---------------------------------------------------------------------------------------

Given

(2x+15)+x=180

Expand parenthesis

2x+15+x=180

Combine like terms

3x+15=180

Subtract 15 on both sides

3x+15-15=180-15

3x=165

Divide 3 on both sides

3x/3=165/3

x=55

Answer:

6,15

Step-by-step explanation:

A dilation is the changing of a size. A scale factor is a proportional number that tells us how much we change a shape.

If the scale factor is over 1, the new image will stretch.

If the scale factor is under 1, the new image will shrink

Since we are asked to find A' (which is prime notation) meaning that we are asked to find the coordinates where A' is at on the new image.

Since the scale factor is 3,

3 is greater than 1 so it will stretch.

Now, multiply 3 to each number

to find it new location.

[tex] \frac{2}{5} \times \frac{3}{3} = \frac{6}{15} [/tex]

So the coordinates are at 6,15

Answer:

I'm pretty sure you multiply each number in (2,5) by the 3 to get new coordinates of (6,15)

that's the only answer that could fit :)

Answer:

1/6

Step-by-step explanation:

We know that 1/2 are apples and 1/3 are bananas

we also know that

apples+bananas+oranges=1

Which means that

1/2+1/3+oranges=1

Add 1/2 + 1/3 by getting the denominators equal

3/6+2/6=5/6

Which means that 5/6+oranges=1

1-5/6=1/6

1/6

write everything below this

1/2+1/3+oranges=1

1/2+1/3=5/6

5/6+oranges=1

oranges=1-5/6

oranges=1/6

Answer:

58

Step-by-step explanation:

First begin with the interest formula.

Interest = Principal x Rate x Time

The $250 is the principal is the amount of money invested.

The rate is 4% which translates to the decimal .04.

The time is 5 years.

So we have I = (250)(.04)(2).

Multiplying, (25)(.04) is 10 and we have 10(2) which is 20.

This means that the interest earned in 2 years is $20.

Answer:

  a.  (1.4, 2.6)

  b.  (3, 2)

Step-by-step explanation:

a. The circumcenter is the intersection point of the perpendicular bisectors of the sides of the triangle.

For points X(a, b) and Y(c, d), the perpendicular bisector of XY can be written as ...

  (c -a)(x -(c+a)/2) +(d -b)(y -(d+b)/2) = 0

Then the equation of the perpendicular bisector of MN is ...

  (-2-4)(x -(-2+4)/2) +(4-0)(y -(4+0)/2) = 0

  -6(x -1) +4(y -2) = 0

  3x -2y = -1 . . . .  divide by -2 and put in standard form

Similarly, the perpendicular bisector of NO is ...

  (0-(-2))(x -(0-2)/2) +(6 -4)(y -(6+4)/2) = 0

  2(x +1) +2(y -5) = 0

   x + y = 4 . . . . divide by 2 and put in standard form

So, the point of intersection is ...

  (3x -2y) +2(x +y) = (-1) +2(4) . . . . . add twice the 2nd equation to the 1st

  5x = 7 . . . . . . simplify

  x = 1.4 . . . . . . divide by 5

  y = 4-1.4 = 2.6 . . . . . find y from the second equation

The coordinates of the circumcenter are (1.4, 2.6).

b. The centroid is the average of the vertex coordinates.

  centroid = (A +B +C)/3 = ((1, 2) +(3, 4) +(5, 0))/3 = (1+3+5, 2+4+0)/3 = (9, 6)/3

  centroid = (3, 2)

Answer:

  y = 2x +5

Step-by-step explanation:

"Gradient" is another word for "slope." The given point (with x-coordinate equal to zero) is the y-intercept. So, it is easy to write the equation in slope-intercept form:

  y = mx + b . . . . . . line with slope m and y-intercept b

  y = 2x + 5

Answer:

I think it's 18 square feet

Answer:

Would be the 3rd one I believe

Step-by-step explanation:

The statement that is true is:

It is one-half the area of a rectangle with sides of 4 units x 3 units is true.

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

The area of the triangle.

= 1/2 x base x height

Now,

Base = 4 units

Heights = 3 units

So,

Area = 1/2 x 4 x 3 = 6 units²

Now,

It is twice the area of a square of the side length of 4 units.

6 units² < 16 units²

This is not true.

It is one-half the area of a square of side length 4 units.

1/2 x 16 units² = 6 units²

8 units² = 6 units²

This is not true.

It is twice the area of a rectangle with sides 4 units x 3 units.

2 x 12 units² = 6 units²

24 units² = 6 units²

This is not true.

It is one-half the area of a rectangle with sides 4 units x 3 units.

1/2 x (4 x 3) units² = 6 units²

6 units² = 6 units²

This is true.

Thus,

It is one-half the area of a rectangle with sides of 4 units x 3 units is true.

Answer:

13.4feet

Step-by-step explanation:

The set up forms a right triangle.

Given

Height of the staircase h = 12 feet

Base of the stairs b = 6feet

Required

Length of the ramp l

Using the pythagoras theorem

l² = h² + b²

l² = 12²+6²

l² = 144 + 36

l² = 180

l = √180

l = 13.42 feet

Hence the length of the ramp to the nearest tenth is 13.4feet
